Self Massage, "The Stick"

Good points. Agree completely with the long warm up. But, do you really think that an advanced athlete, with good mobility, will suffer microtears from performing bodyweight lunges?
I think organized warm-ups is one of the most important concepts forgotten by coaches. Most just have their athletes move around a lot and perform some drills they saw on a video or some other coach doing. A proper warm-up progresion is vital.

no matter how elite, motion cold is likely to result in problems…it’s not so much the stress level but the tissue preparation.

I agree, from my own experience I prefer to jog 3-4 laps of the track before performing any type of stretching. If I just do dynamic stretching my muscles feel hard and inflexible and stretching is painful, rather than the usual stretching sensation.
